* This example requires the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Rest')
loRest = CreateObject('Chilkat.Rest')

* Connect to the Amazon AWS REST server.

* Important: For buckets created in regions outside us-east-1,
* there are three important changes that need to be made.
* See Working with S3 Buckets in Non-us-east-1 Regions for the details.

* Provide AWS credentials for the REST call.
